[Samba] Deny a User from a specific Host

[Net Warrior]

HI there guys.
Is there  a way to control the machines where a user can login?
I've got a pdc with ldap, and I've got some department, and I do not want
users from , for example devel dept , go to marketing dept
and login using those machines..

Novell netware has something like that, but no Idea if I can achieve this
with samba.

Thanks in advance.
